Tower theorem

In mathematics, Dehn's lemma asserts that a piecewise-linear map of a disk into a 3-manifold, with the map's singularity set in the disk's interior, implies the existence of another piecewise-linear map of the disk which is an embedding and is identical to the original on the boundary of the disk. This theorem was thought to be proven by Max Dehn (1910), but Hellmuth Kneser (1929, page 260) found a gap in the proof. The status of Dehn's lemma remained in doubt until Christos Papakyria… WebTitle: Higher Algebraic Closure Speaker: Theo Johnson-Freyd (Dalhousie University Perimeter Institute) Abstract: The fundamental theorem of algebra, as Hilbert explained, asserts that every consistent system of polynomial equations over R has a solution over C.
